The day after July 4th 🇺🇸, the first commit for dotenv was made and version 0.0.1 was released on npm. In the 11 years since, dotenv has become an integral part of the software development landscape, with widespread usage comparable to TypeScript and ESLint. Despite its initial humble beginnings, dotenv has grown to be a beloved tool for millions of developers, significantly enhancing security with minimal hassle.
However, dotenv is not without its problems. There are three primary issues which pose varying degrees of security risks. The most significant of these problems is the potential leaking of environment variables.
To address these challenges, dotenvx has been introduced as the next generation of configuration management. Here’s a deep dive into the three main solutions provided by dotenvx:
Run Anywhere
dotenvx ensures consistent behavior across different languages, frameworks, and platforms. By using the command `dotenvx run -- your-cmd`, developers can inject their environment variables at runtime. This unified approach eliminates inconsistency issues and provides the same functionality for Python apps, Node apps, and Rust apps alike.
Developers can install dotenvx via npm, brew, curl, docker, windows, and more, ensuring easy access and seamless integration into various development workflows.

Install dotenvx via various methods for streamlined setup and consistent behavior across platforms.
Multiple Environments
Managing multiple environments becomes straightforward with dotenvx. Developers can create a `.env.production` file and use the `-f` flag to load the desired environment configuration. This feature was particularly inspired by community suggestions and effectively resolves the complexity of juggling multiple environments directly from the command line.
Additionally, dotenvx allows the composition of multiple environments using multiple `-f` flags, offering flexibility and convenience.
Encryption
Encryption is the game-changing feature that establishes dotenvx as the next-gen configuration management tool. By running the command `dotenvx encrypt`, developers can add encryption to their .env files. This process generates a DOTENV_PUBLIC_KEY for encryption and a DOTENV_PRIVATE_KEY for decryption using public-key cryptography akin to Bitcoin.
Even if a .env file gets leaked, it’s useless without the DOTENV_PRIVATE_KEY. This approach not only protects sensitive information effectively but also allows contributors to add configurations without decrypting existing secrets. This is particularly beneficial for open-source projects where maintaining confidentiality is crucial.

1.0.0 Release
With the latest version 1.0.0, dotenvx promises users enhanced security and efficiency in managing their environment configurations. As the landscape of software development evolves, dotenvx is set to steer it towards a brighter, more secure future.
